Esterified tocopherols and tocotrienols in rice bran oil, soybean oil, and sesame oil were separated from free tocopherols and tocotrienols by TLC. After saponif ication of the esters, free tocopherols and tocotrienols were determined by high performance liquid chromatography. Refined rice bran oil contained 40μg/g of α-tocopherol, 3μg/g of, β-tocopherol, 3μg/g of γ-tocopherol and 5μg/g of γ-tocotrienol, Refined soybean oil also contained 3μg/g of γ-tocopherol and 3μg/g of δ-tocopherol, α-Tocopherol (7 μg/g) occurred as an esterif ied form in commercial sesame oil.
